【摘要】 通过分析单台长期地磁场扰动幅度和地磁行星指数Ap和Kp关系,对1小时磁扰幅度r_H的日平均与Ap进行拟合,快速估算Ap指数。对3小时内r_H的平均与Kp进行对数拟合,估算Kp指数。采用肇庆地震台2003—2008年地磁H分量分钟值数据,估算行星Ap和Kp指数,与世界数据中心(WDC)给出的Ap和Kp指数进行统计分析。结果发现,根据上述方法,利用肇庆地震台地磁数据估算Ap和Kp指数,在一定误差范围内可行。更多还原

【Abstract】 By analyzing the relationship between the disturbance amplitude of a single geomagnetic station s data and the geomagnetic planet indices of Ap and Kp for a long time,a fast and simple method for the Ap estimation on fitting the daily average of one hour disturbance amplitude of magnetic is presented.Based on the logarithmic fitting of the Kp and the average of r₁₁in three hours,we can get the estimating method of Kp index.According to the above mentioned methods,using the geomagnetic minutes data of H component from 2003—2008 of Zhaoqing station to estimate the planetary indices of Ap and Kp,and comparing with the Ap and Kp indices from the Word Data Center.Results show that,in accordance with the above method using the Zhaoqing geomagnetic data to estimate Ap and Kp indices is feasible in a certain error range.更多还原
